4.7. Manual SSIS


The manual SSIS workflow is designed for manual sequence stratigraphic interpretation. Currently, a body can be extracted from a drawn polygon. A polygon can outline a geobody e.g. channel, valley, or other geomorphological feature. Extraction of such bodies is important for in-depth stratigraphic interpretation. By doing this, the volume is limited through drawing a polygon where after different attributes can be displayed on-the-fly, which in turn can be interpreted further. The workflow is as follow:

1- Create a new polygon that defines a geological shape.
2- Right-click on the new polygon name and select Create body
3- In the pop-up window select the top and bottom horizons to define a vertical limit. Press OK to continue

The setup will create and display the output body. An example body of sand-waves from offshore seismic data is shown below.
